Within the for loop, create a variable called arrayChunk and set it equal to the chunk of the array going from the current loop index to the current loop index plus size . You an use .slice() to accomplish this.

I don’t understand this point and have no clue how to code it.
This is my code:

Maybe the what and the how are the same thing. That is also how to do it.

You could try using pen and paper to make yourself go through all the required actions (which are probably incredibly obvious when you do it, but perhaps only because this time you really work through it)
